Product details
Overview
F2800156QPNRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified real-time microcontroller featuring dual 32-bit C28x CPUs in lockstep at 100MHz, IEEE 754 FPU, TMU, and VCRC engine. It integrates 256KB ECC-protected flash, 36KB ECC/parity-protected RAM, two 4MSPS 12-bit ADCs, 14 ePWM channels (4 with 150ps resolution), one CAN FD (MCAN) port, and functional safety support up to ASIL B for motor control in DC/DC converters and HVAC compressor modules.
For engineers reviewing the F2800156QPNRQ1 datasheet, F2800156QPNRQ1 pinout, F2800156QPNRQ1 application, or F2800156QPNRQ1 equivalent, key selection criteria include its 100MHz dual-core lockstep operation, ASIL B certification, 80-pin LQFP package with 52 GPIOs (11 shared with analog), and integrated high-resolution PWM for power electronics timing-critical control loops.
Technical Context
The F2800156QPNRQ1 implements a dual-C28x CPU architecture operating in lockstep to enable hardware-level fault detection without software overhead, meeting ISO 26262 ASIL B requirements. Its real-time subsystem includes dedicated accelerators: Trigonometric Math Unit (TMU) for fast sine/cosine computation and VCRC engine for rapid CRC-16/32 generation in communication and firmware integrity checks.
System-level timing is managed by dual internal 10MHz oscillators, crystal/external clock input, windowed watchdog timer, missing clock detection, and Dual-Clock Comparator (DCC). Analog signal chain performance is enhanced by tight coupling between two 4MSPS ADCs, four post-processing blocks per ADC, and one CMPSS with 12-bit DAC plus three CMPSS_LITE modules with 9.5-bit DACs.

FAQ
What is the maximum operating frequency of the F2800156QPNRQ1?
The F2800156QPNRQ1 operates at a maximum CPU frequency of 100MHz across both C28x cores in lockstep configuration. This frequency is fixed by the device's PLL and internal oscillator architecture, and it is validated for reliable operation across the full –40°C to 125°C ambient temperature range. The 100MHz speed enables sub-10μs current control loops essential for SiC/GaN-based power converters. F2800156QPNRQ1 does not support dynamic frequency scaling or overclocking beyond this rated speed.
Does the F2800156QPNRQ1 support CAN FD communication?
Yes, the F2800156QPNRQ1 includes one Controller Area Network with Flexible Data-Rate (CAN FD/MCAN) port compliant with ISO 11898-1:2015. It supports data rates up to 5Mbps, payloads up to 64 bytes, and CRC-17/21 error detection. This interface is fully integrated with the device's DMA and interrupt subsystem, enabling efficient message handling in automotive ECUs such as HVAC compressor controllers and OBCs. F2800156QPNRQ1 implements the MCAN module type 2 as specified in the device comparison table.
What package and pin count does the F2800156QPNRQ1 use?
The F2800156QPNRQ1 uses an 80-pin Low-profile Quad Flatpack (LQFP) package, designated by the "PN" suffix in its orderable part number. Its physical dimensions are 14mm × 14mm with a 12mm × 12mm body size. This package provides 52 general-purpose I/O pins (11 shared with analog functions), 4 JTAG debug pins, and dedicated power/ground connections. F2800156QPNRQ1 is not offered in smaller packages like RHB or PHP - only PN and PM variants are listed for this specific part number in TI's official documentation.
How does the F2800156QPNRQ1 achieve ASIL B compliance?
The F2800156QPNRQ1 achieves ISO 26262 ASIL B compliance through hardware-level lockstep dual-C28x CPU execution, built-in memory ECC/parity protection, windowed watchdog timer, missing clock detection, and Dual-Clock Comparator (DCC). These features were verified by TÜV SÜD and documented in TI's functional safety package. F2800156QPNRQ1 does not require external safety monitors or redundant controllers to meet ASIL B - its integrated diagnostics cover CPU, memory, clock, and reset domains as defined in the safety manual.
What analog peripherals are integrated into the F2800156QPNRQ1?
The F2800156QPNRQ1 integrates two independent 12-bit analog-to-digital converters (ADCs), each capable of 4MSPS sampling, with up to 21 total external input channels (11 shared with GPIO). It also includes one full-featured Comparator Subsystem (CMPSS) with two comparators and two 12-bit DACs with ramp generators, plus three CMPSS_LITE modules with 9.5-bit DACs. These analog resources are tightly coupled to PWM and capture peripherals, enabling real-time overcurrent protection and fast current-loop closure without CPU intervention. F2800156QPNRQ1 does not include DACs beyond those embedded in the CMPSS blocks.
